WINDOW-BASED CONGESTION CONTROL

Examples described herein relate to a network interface device that includes circuitry to cause transmission of a packet following transmission of one or more data packets to a receiver, wherein the packet comprises one or more of: a count of transmitted data, a timestamp of transmission of the packet, and/or an index value to one or more of a count of transmitted data and a timestamp of transmission of the packet. In some examples, the network interface device includes circuitry to receive, from the receiver, a second packet that includes a copy of the count of transmitted data and the timestamp of transmission of the packet or the index from the packet. In some examples, the network interface device includes circuitry to perform congestion control based on the received copy of the count of transmitted data and the timestamp of transmission of the packet.
